Gleaner R75 Combine Parts

R75 parts and accessories

The Gleaner R75 combine, produced from 1997 to 2006, was a popular choice for farmers seeking reliable grain harvesting performance. Equipped with engines ranging from 260 to 300 HP and capable of handling header widths up to 36 feet, the R75's rotary separator system provided efficient threshing and separation. Known for its simplicity and durability, the R75 became a mainstay on farms across North America.

The Gleaner R75 combine harvester was introduced in 1997 and remained in production until 2006. It was powered by a range of engines, primarily Cummins diesels, with horsepower options typically ranging from 260 to 300 HP, depending on the year and specific configuration. Engine displacement varied, but common sizes included 8.3L and 9.0L options. The R75 utilized a transverse rotary threshing and separating system, featuring an axial rotor that provided gentle grain handling and efficient separation of grain from the straw. Grain tank capacity was around 300 bushels, and the unloading auger could unload at a rate of approximately 2.5-3 bushels per second, or 150-180 bushels per minute. Available header widths spanned from narrow row crop heads to wider platforms up to 36 feet for small grains. Options included straw choppers and spreaders for residue management. The cab was designed for operator comfort and visibility, featuring air conditioning, adjustable seating, and intuitive controls. The Gleaner R75 was particularly effective at harvesting corn, soybeans, wheat, and other small grains, making it a versatile machine for diverse farming operations.

Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance based on the crop being harvested. Proper concave settings are crucial for efficient threshing and minimizing grain damage.
Belt and Chain Tension: Inspect and maintain proper tension on all belts and chains. Loose belts or chains can lead to slippage, reduced performance, and premature wear.
Sieve and Chaffer Cleaning: Clean the sieves and chaffer frequently to remove debris and prevent plugging. Clogged sieves can reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Regularly grease all bearings according to the manufacturer's recommendations. Proper lubrication is essential for preventing bearing failure and extending the life of the combine.
